SPECIFICATION forming part of Letters Patent No. 446,672, .dated February 17, 1891.

Application filed .Tune l2, 1889. Serial No. 314,040. (No model.) Patented in England September 23, 1889, No, 14,994.

To all whom t may concern:

Be it known that l, STERLING ELLIOTT, of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improvenient in Velocipedes, (for which Letters Pat-- ent have been granted in England, No. 14,994, dated September 23, 1889,) of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

rlhis invention has for its object to construct a velocipede of the type commonly called Safety bicycles3 and the invention consists in various details of construction to be 'hereinafter described.

Figure l shows in side elevation and partial section a velocipede embodying this invention; Fig. 2, an enlarged vertical sectional detail of the steering-wheel support, showing its pivotal connection with the traine, Fig. 2", a detail to be referred to, Figs. 3 and 4, sectional details ot' the pedals to be referred to; Fig. 5, a detail of the handle-bar; Figs. l, 7, and 8, details ot' the seat t-o be referred to; Fig. 9, a longitudinal sectional detail of the hub oi' the driving-wheel; Fig. l0, an enlarged cross-sectional detail of the axle; Fig. ll, au end view of' the seat-supporting collar on the axle, Fig. l2, an enlarged detail of the hanger or carrier for the driving-crank; Fig. 1.3, a vertical sectionof the sprocket-wheel and attached pedal-lever; Figs. let and l5, details of the brake-lever; Figs. 1G and l?, details ot' the guard for the sprocket-wheel, and Fig. 1S a detail to be referred to.

'lhe main frame-work ot the machine coinprises a tubular bent bar a, having at its front end a downwardly-extended projection or pintle d and an upwardly-extended projection c2, having a socket or recess.

rlhe steering-wheel support consists of the tubular bar b, preferably rearwardly inclined and having secured to its lower end a steering-fork b', said tube also having formed on it arms b2, to which is secured a guard b3 for the steering-wheel c, which is journaled in the steering-fork. The arm b2 has a boss b3 formed on it, (see Fig. 2,) provided with a socket or recess to receive the pintle a. A tube Z1 has alsoa projection b4, through which a screw if passes, the end of which is slightly tapered to fit the socket or recess in the proj ection a2 of the frame. It will be seen that the end of the screw h5 and the pintle a serve as the pivots for the steering-wheel support, and by directing the said pivots downwardly, as shown, affords sockets or recesses open at the top to retain the oil. A tube c is held adjustably in the tube b, and to the upper end of said tube c is attached a collar or cap c2, from which extend the steering-handles c3 c4, or they may be attached to it. A split ring y (see Figs. 2 and 2) is placed on the projection d2, said ring having at one side or at its ends ears y', through one of which ears a screw 'J2 passes freely and is turned into and held in the other ear. A spring yg is placed on the shank of the screw y2, one end of which bears against the head of the screw and the other end bears against that ear y which is free on the screw, the function of said spring being to press said ear toward the other ear, and hence to hold the ring frictionally in place. The ring y has on it a lug g4, which enters a recess formed in the rear side of the tube ZJ, so that as the tube is turned the ring g/ will be turned by it, but owing to its friction will serve as a retarding device therefor.

At the rear end of the tubular traine d recesses are formed at each side to receive bars d, preferably of wood, arranged side by side, and which constitute a fork for the rear or driving wheel e. Arins d are also formed on the tubular bar d at its rear end, to which is attached a wooden guard f for said rear or driving wheel.

The wooden guard f (shown as tapering from end to end for flexibility) extends over the rear or driving wheel, so as to inclose substantially one-half of said wheel, and ata point above the wheel brace-rods, asf', are attached, the lower ends of which enter sockets formed in the projections i on the collar i', placed on the driving-axle at or near each end. (See Figs. 9 and ll.)

The hub e of the wheel e is preferably made of wood and the wheel has wooden spokes e2. Metallic caps c3 are secured to the hub at each end, said caps having flanges ci, which receive the collars i', a washer being preferably interposed. The collars are held in position on the axle by nuts a', which bear upon suit- IOO able washers resting against the bars d, which in order bear against the collars.

The axle, which is stationary, is grooved at its upper side, as at n2, from at or near xone end to a point substantially at the center of the hub, and a thin bar or strip nl* (see Fig. 10) is rabbeted in said groove, so as to leave or present a chamber beneath it, said bar or strip terminating near the inner end of the gi'oove to leave an opening through which oil placed in said groove may escape. A passage n5X is formed in the collar i', which communicates with the groove n2,-the entrance toY said passage being at the projection 3, formed on the collar t', for the admission of oil. The axle n has also a longitudinal groove n eX- tending substantially its entire length and at one side of the groove/n2. A felt, wicking, or other absorbent material is placed in said groove and the oil from the groove n2 works around the axle and is taken up by the absorbent material. A cap 716 is fitted into the oil hole or passage.

One of the metallic caps or end pieces c3 has sprocket teeth c6, over which passes a sprocket-chain m, which chain also passes over a sprocket-wheel on', journaled in a hanger, carrier, or loop like bracket m2, con- .nected to the tubular frame a by a pin 2.

'passes through a projection m5 on the under side of the frame a, said rod receiving upon its screw-threaded portion nuts m, by which the loop-like hanger or carrier is held in position and adjusted for the purpose of tightening the driving-chain.

One of the pedal bars or arms, as 0, is attached to the hub of the sprocket-wheel in', (see Fig. 13,) and the other pedal'bar, as 0X, is attached to the shaft carrying the sprocketwheel, and the pedals are loosely connected to the pedal levers or arms o 0X, each pedal consisting ot' a frame o', (sec Figs. 3 and 4,) suitably recessed to receive a bolt o2, which serves as a bearing for pedal. The frame o has at one end a ilange 03, which receives within it a screw7 o, by which the pedal is held on the arm or bolt, and to effectuallv exclude dust a disk or screw o5 is screwed into the said flange o3. The frame o has secured to it at each edge a rubber plate oi by means of metallic plates 07 and screws or bolts o8. The frame o has on it projections o, and also a projection 010, having an oil-passage through it.

The brake mechanism consists of the lever t, (see Figs. 1, 14, and 15,) pivoted at t to the guardf, and having at its lower end a brakeshoe t2. The said lever t has at its edge aseries of pins 153, and also has at its upper end a hole through it for the brake-chain t4, which has one or niore hooks t5, which engage one or more of the pins t3. The brake-chain t4 passes through the tubular frame ct over the pulley t, thence through the steering-wheel support b over the pulley 7, thence up through the tubular support c', and atits upper end is connected at one end to the handlever t8, pivoted to the handle-har As the lever t8 is depressed, the brake-chain will be drawn and the lever t moved.

The seat-post a (see Figs. 1, G, 7, and 8) is adjustably held in a socket or holder u', secured to the frame j. A plate or carrier u2 is placed on the posta and held by a pin a3, passing through it. Two screwsu* pass through the plate u2 at each side of the post an'dbe'ar against the post at each side, as shown in Fig. 6. By turning one or the other screw the p late or carrier fa is tilted. Two springs u it are attached to the plate or holder, one at each side, said springs each having outwardlyextended arms al, which arins pass over hooks ux and enter ears formed on the saddle-frame u8, being held in place by set-screws M20. The opposite ends of the springs i1/5 u en tera block u, supported on a screw um, having its bearing in the frame an. By means ot" the screw uw the two frames u8 and um are moved toward or from each other to stretch the material ot' the seat uw. The socket in the frame M12, which receives the end ot the screw um, is made considerably larger than the cross-sectional area of the screw to thereby aiord considerable play for the seat.

The cover for the seatis formed of leather or other suitable material, it being riveted to the frame u8, and -having a gore removed at the front to enable the end to be contracted, said end being carriedoverthe fraineu12 and secured by joining the edges of the recess by stitches, as shown in Fig. 1S.

v It will be seen that the seat-post is vertically adj ustablc, the seat-plate or carrier u2 yields, and the spring-arms a5 u, by means ot' the eyebolts by which they are attached, may be moved back and forth.

A guard lw is secured to the frame,inclos ing or concealing the sprocket wheel and chain, and another guard w is attached to the guard w, (see Figs. 16 and 17,) which partially covers or incloses the sprocket-wheel.

The tubular traine a is so bent or curved as to be touched interiorly by the brake-chain to thereby prevent the said brake-chain from rattling.
